...issues involved in producing engineering housings. A housing can be defined as an “envelope designed to retain and position a range of mechanical or electrical components”1. More specifically, the aim of this essay is to discuss what aspects need to be considered when determining which materials and processes are to be used in the manufacture of a car engine cylinder block (which is considered to be a housing). First of all, an identification of the developments, difficulties and constraints introduced by the design requirement to cast (or mould) a housing will be done. Secondly, a comparison of the material/process choices between ferrous alloys and light alloys for housing applications will be developed. Thirdly, the finishing, joining and assembly aspects will be identified and finally, this essay will be ended by a discussion about how the overall organisation of the manufacturing system might be expected to change with production from cast iron to aluminium alloy engine blocks and how the manufacturer has accommodated these changes within their overall manufacturing strategy.

Task: Develop a social responsibility strategy for your chosen client which includes the following components: 1. Environmental considerations and recommendations 2. Ethical leadership considerations and recommendations 3. Sustainability considerations and recommendations 4. Legal and regulatory considerations and recommendations Note: This may be a strategy for the company's current product line or service and current business objectives, or it may be a strategy that recommends a new direction for the company. Step 1: The company I work for is an iron foundry. The company makes cast iron parts for other industries. This involves industrial marketing of iron casting. Usually, the castings are sold to other plants within the same industrial area. This cuts down the transportation cost. Step 2: There are serious environmental considerations which include: the furnace, degassing, and pouring all produce toxic fumes. The surface cleaning and finishing produces pollutants that are released in drain water. The social responsibility...

...The history and evolution of materials used to make automotive engine blocks The engine is an essential part of an automobile that provides tractive force to drive the entire vehicle. Most of the current engines are the integral section of a vehicle which is built in different arrangements and more complex as compared to the early engines. The common parts present in an engine include camshaft, rocker arms, pistons, crankshaft, flywheel, both oil and fuel pumps and other various components. The discovery of both light, as well as stronger engineering materials in manufacturing different parts of an engine, has had an impact on power to weight of the engine thus making the entire automobile very light. An engine block or else cylinder block is the base of an engine that accommodates about all the parts needed for an engine to perform properly. There exist mainly three configurations of an engine block, that is, horizontally-opposed, “V”- shaped as well as inline configurations. The number of cylinders within these block configurations varies from a minimum of two to a maximum of sixteen depending on the power needed. Since an engine block is the most significant part of an engine, it should satisfy quite many functional requirements. The functional requirements include; 1. Housing of the moving components and the fluids, 2. Enduring the varying thermal pressures generated during combustion process, 3. Making the automobile last longer, 4. Maintaining of the engine...

...Unit Title: Manage Human Resources Strategic Planning Read the following case study on “Kangaroo Foundry Castings”. Answer the 5 questions below: Kangaroo Foundry Castings was established by Nav Suderland in the late 1930’s after the Great Depression. His vision was to provide Australian-made iron castings at a time when they were imported from Britain. The Business, based in South Wollongong in New South Wales (NSW), produced casting lamp posts and manhole covers for the sewerage system. It also catered to the needs of the defence forces during the Second World War. Additional contracts also came from government client’s including the NSW railways. The business is now owned and managed by the third generation of the family – two brothers and one of their cousins. This team has been running the business for the past 20 years and make all the decisions. They still do business with the government departments. They have been investing in updating their plant and equipment. A major portion of the business comes from small private manufacturers who need iron casting parts for their products. The transport cost of delivering the raw materials has also gone up and the local government has imposed strict regulations because manufacturing the castings has a direct impact on the environment. Most of the Kangaroo Foundry Casting’s customers are no longer in NSW due to tough competition. The demand for their products has changed. Their customers are now looking for cheaper...

...Warehouse function Historically warehouses were a dominant part of the urban landscape used from the start of the Industrial Revolution through the 19th century and into the twentieth century: the building remained when their original usage had changed. There are four identifiable types of warehouses. The cotton industry was co-terminus with the development of the warehouse, and all five types were represented in Manchester, United Kingdom. Warehouses in Manchester were often lavishly decorated juxtaposing with the modern view of warehouses which are assumed to be standard industrial buildings. Display of Goods for Sale These displayed goods for the home trade. This would be finished goods- such as the latest cotton blouses or fashion items. There street frontage was impressive, so they took the styles of Italianate Palazzos. Richard Cobden's construction in Mosley Street was the first palazzo warehouse. There were already seven warehouses on Portland Street when they commenced building the elaborate Watts Warehouse of 1855, but four more were opened before it was finished. It was this type of warehouse that inspired the Germans in Duesseldorf and Muenchen to name their prestigious departmental stores, 'Warenhausen'. Overseas Warehouses These catered for the overseas trade. They became the meeting places for overseas wholesale buyers where printed and plain could be discussed and ordered. Trade in cloth in Manchester was conducted by many nationalities. Behrens Warehouse...

...Ironworks is a job shop specializing in heavy duty gray iron castings which is not a “growth industry” in Detroit in 1973. One particularly troublesome department is the raw castings foundry. The average hourly wage rate in the foundry is approximately $3.85 and the fringe-benefit package is about 20%, based on paid wages. The base rate is $3.75 and there is a $50 per hour raise after four months, for those who stick around that long. The job requires a very strong back, a high tolerance for dismal working conditions, and very little else. The foundry is hot, dirty, dark (except for the blinding flames from the furnaces) and rat infested. The normal production crew is 125 men on each of two shifts, or 250 men in total. Usually, about 122 of the 125 scheduled workers actually come to work. Profit margins have been steadily declining in recent years and are now at dangerously low point. Gray iron foundries in Detroit are closing in droves in the early 1970s due to declining auto industry, the move to lighter materials (alumunium vs. iron) induced by the oil “crisis”, the depressed “rust bell” economy in general, and a trend to new materials technologies. Those foundries that remain have good backlogs because they are picking up the extra volume from those that close. But, trying to raise prices just increases the rate of defecting customers even more. For companies that want to stay in the business, the trick is to accept iron casting prices (or maybe even cut them!) and learn how...

Marszalek, K. Kubiak Faculty of Mechanic Engineering and Aeronautics, Rzeszow UniÕersity of Technology, 35-959 Rzeszow, ul. W. Pola 2, Poland ´ ´ Received 9 August 1999; received in revised form 17 February 2000; accepted 17 February 2000 Abstract The main objective of this paper is to study and experimentally quantify the cam and follower wear mechanisms of a diesel direct valve-gear. Camshafts are made of nodular cast iron, surface hardened, ion nitrided and nitrosulphurized, and those made of grey chilled cast iron are mated with followers made of chilled grey cast iron and hardened steel. The investigation was carried out on a laboratory bench equipped with an engine head with a camshaft, followers and systems creating the conditions necessary for a routine run of the valve gear. Cam wear was defined by comparing the profile lifts of the cams. The height of the followers was measured using a coordinative measuring machine and a perpendicular optimeter. The rotational speed, valve displacement and the torque required by the valve gear were measured. Camshaft C9 and the thimble shaped followers with regulating plates F6 were also examined in a diesel engine. The effects of the materials the kinematic pair was made of, heat treatment and thermochemical treatment,...

...until dough is smooth. Divide dough into 10 equal pieces, rolling each piece into a ball. Allow to rest, covered with plastic wrap, for at least 30 minutes. 2. Once dough has rested, preheat cast iron skillet over medium-high heat (do not use nonstick for this). Roll out each ball into a circle, about 6 inches in diameter. Cook one at a time in the hot skillet for about 60 seconds, flipping half-way through, when it starts to puff and a few brown spots have appeared on the first side. Keep warm by wrapping the stacked tortillas in a clean dishcloth. Bottom of Form Description Make your own fast and easy wraps/tortillas Summary | | | | | | Ingredients 2 | Cup | flour | 1⁄2 | Teaspoon | salt | 1 | Cup | water | 3 | Tablespoon | oil | Instructions 1. In a large bowl, mix flour and salt. Add water and oil. Stir until it sticks together to make a dough ball. More flour may need to be added until it sticks together. 2.

...writing has an undertone of romance with chivalry and gentlemanly ways that never went out of style. In “The Man in the Iron Mask”, the third book in “The Three Musketeer Trilogy”, Dumas wrote about bonds that were indestructible. During Dumas’ youth, he battled poverty, lack of education, and racism. “A gentleman once began to make racist remarks within earshot, and when he finally said, “Mr. Dumas probably knows a thing or two about Negroes, since so much black blood runs in his veins,” Dumas coolly responded, “Yes, of course. My father was a mulatto, my grandfather was a Negro and my great-grandfather was an ape. You see, sir, my family began where yours left off.”(Foote-Greenwell p. 2). “In 1823 Dumas moved to Paris with nothing but his wits, memory and elegant writing. He got a job as a...

...on April 1, 1917. Scott Joplin (1867/1868 – April 1, 1917) was an African-American composer and pianist. Joplin achieved fame for his ragtime compositions and was dubbed the "King of Ragtime Writers". During his brief career, he wrote 44 original ragtime pieces, one ragtime ballet, and two operas. One of his first pieces, the "Maple Leaf Rag", became ragtime's first and most influential hit, and has been recognized as the archetypal rag. "Scott Joplin." Bio. A&E Television Networks, 2015. Web. 30 Mar. 2015. www.youtube.com/watch?v=pMAtL7n_-rc The story of the piano begins in Padua, Italy in 1709, in the shop of a harpsichord maker named Bartolomeo di Francesco Cristofori (1655-1731). Many other stringed and keyboard instruments preceded the piano and led to the development of the instrument as we know it today. Cristofori's piano was developed from the harpsichord and consequently rather small and made entirely out of wood. As time passed, however, the development of larger instruments with more and heavier strings at higher tensions - all in order to increase the volume of sound - necessitated a more rigid construction. The wooden frame was successively reinforced with more and more pieces of iron, and in 1825 the complete cast iron plate was introduced by the American piano maker Babcock. The iron plate could withstand the increased string tension, and prevented the...

...The Soul of the Great Bell by Lafcadio Hearn (1850-1904) The water-clock marks the hour in the Tachung sz’, in the Tower of the Great Bell: now the mallet is lifted to smite the lips of the metal monster—the vast lips inscribed with Buddhist texts from the sacred Fa-hwa-King, from the chapters of the holy Ling-yen-King! Hear the great bell responding!—how mighty her voice, though tongueless! KO-NGAI! All the little dragons on the high-tilted eaves of the green roofs shiver to the tips of their gilded tails under that deep wave of sound; all the porcelain gargoyles tremble on their carven perches; all the hundred little bells of the pagodas quiver with desire to speak. KO-NGAI—all the green-and-gold tiles of the temple are vibrating; the wooden goldfish above them are writhing against the sky; the uplifted finger of Fo shakes high over the heads of the worshippers through the blue fog of incense! KO-NGAI!—What a thunder tone was that! All the lacquered goblins on the palace cornices wriggle their fire-coloured tongues! And after each huge shock, how wondrous the multiple echo and the great golden moan, and, at last, the sudden sibilant sobbing in the ears when the immense tone faints away in broken whispers of silver, as though a woman should whisper, “Hiai!” Even so the great bell hath sounded every day for well-nigh five hundred years—Ko-Ngai: first with stupendous clang, then with immeasurable moan of gold, then with silver murmuring of “Hiai!” And there is not a child in...
